CULTIVATOR- SPECIFICATION forming part of Letters Patent No. 272,701, dated February 20, 1883. Application filed September 1, 1882. (No model.)

1'0 all whom it may concern:

Be it known that l, FRANK H. JOHNSON, a. subject of the King of Sweden, and residing at Biggsville, in the county ofHenderson and State ot' Illinois, U. S. A.. have invented certainnew and useful Improvementsin Cultivators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accom panying drawings, and to the letters and figures of reference marked thereon, whichform a. part of this specification.

This invention relates to certain new and useful improvements in cultivators; andit consists in the peculiar construction and arran geinent of parts, as willbe hereinafter more fully set forth.

In the annexed drawings, Figure 1 is a perspeotive view of one-half of the cultivator. Fig.2 is a bottom plan view. Fig.3 is a vertical central section. Fig. 4 shows a perspectiqe view of the wedge-shaped washer. Fig. 5 is a side view of the beams and washer in place, and Fig. 6 detail views.

, A represents a beam, to which is attached a series ot'shovels or cultivator-teeth, B, ot'the iorm shown in the drawings or any other of the usual forms in use. 'These shovels are riveted or otherwise secured to the standards a a,which extend through the beam A. These standards aare secured to the beam A by can be adjusted vertically.

To the centerot' the beam A, on its upper side, is bolted or pivoted a beam, 0, which is. connec'ed at its forward end by means of a clevis, bolt, or other coupling to the main axle of any wheel-cultivator. WVhen the beams are manufactured they are preferably made plain at the end. so that the user can apply any form of connection.

1) is a handle securely attached to the beam 0 by means ofa brace and bolts.

A brace-rod, E, is secured to the under sides of the beams A and (J, and connects them. One end of said brace is pivoted to the under side of the beam 0 at d, (see Fig. 2,) some distance from the beam A. The other end is provided with a number of holes, e, by means of which and a bolt or rivet the brace is adjustably attached to the under side of the beam A, near one ofits outer ends. (See Fig. 2.) By this means the angle of the beams with each other is varied, or, in other words, the cultivator is extended or narrowed. The beam 0 is pivoted to the beam A by a bolt,f, whose head is countersunk in the beam O, and itsend projecting through the beam Ais screw-threaded, and receives a washer and nut,h, by means of which the beams are tightened. Around this boltf, and between the beams, is placed a wedge-shaped washer, F, (see Fig. 4,) which is provided with a radial slot or opening, 9, by means of which the washer is placed around the boltfand turned to give different angles to the beam 0 to .suit the heights of the axles of different cultivators. (See Figs. 3 and 5, where the washer is shown turned atdifl'erent angles.)

In orderto varytheinclinationof the shovels B, wedge-shaped washers F, similar in construction to the washer under the beam 0, may be placed around the standards a, on top of the beam A and under the nuts 0, as shown in Fig. 6. When the shovels are designed to remain at one angle only the plain washers (shown in Fig. 1) take the place of the wedgeshaped ones.

In Fig. 1 are shown the beams, handle, and shovels for oneside only of a cultivator, the design being to have a similar arrangement. for the other side.

It will be observed that by using proper teeth'in the beam A the device may be converted into a barrow.

Having thusdescribed my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination ofthebeam O,boltf, wedgeshaped washer F, provided with the radial slot or opening g, the beam A. and bar E, substantially as shown and described.

In testimony whereof I aflix my signature in presence of two witnesses.

FRANK H. JOHNSON.
